What company is this? I assume you aren't referring to the defunct exchange.

ETC Group has recently launched the first physically backed Bitcoin
ETC listed on Deutsche Börse /Xetra, Europe’s largest ETF exchange
and one of the world’s top 10 stock exchanges. BTCE is distributed in
cooperation with HANetf and will be passported across several
European countries.

BTCetc – Bitcoin Exchange Traded Crypto (primary ticker: BTCE) allows investors to track the price
of Bitcoin, just like a share of a company on a stock exchange. BTCE is fully backed by physical Bitcoin,
held in cold storage with a regulated custodian and security over the collateral account is held by a trustee
for additional investor protection.
